Exodus 7:19

19 And the Lord said to Moses, Say to thy brother Aaron, Take thy rod in thy hand, and stretch forth thy hand over the waters of Egypt, and over their rivers, and over their canals, and over their ponds, and over all their standing water, and it shall become blood: and there was blood in all the land of Egypt, both in vessels of wood and of stone.

Exodus 7:19 Meaning and Commentary

Exodus 7:19

And the Lord spake unto Moses
Pharaoh still being obstinate, and refusing to let the people go:

say unto Aaron, take thy rod, and stretch out thine hand upon the
waters of Egypt;
upon all of them in general, what were in the river Nile, or derived from it, as follows:

upon their streams;
the seven streams of the river Nile, (See Gill on Isaiah 11:15).

upon their rivers;
the canals that were cut out of the river Nile, for the watering of their fields and gardens, for they had no other river:

and upon their ponds, and upon all their pools of waters;
which were dug near the river, or to which pipes were laid to convey the water thither:

that they may become blood;
and so not fit to drink:

and that there may be blood throughout all the land of Egypt,
both in vessels of wood, and in vessels of stone;
in which water were kept in private houses, fetched from the river for the use of families; all which were to be turned into blood everywhere, in all parts of the land, and in all places mentioned, immediately upon Aaron's taking his rod, and smiting the waters with it in that part of the river that was before him.

Exodus 7:19 In-Context

17 These things saith the Lord: Hereby shalt thou know that I am the Lord: behold, I strike with the rod that is in my hand on the water which is in the river, and it shall change it into blood.

18 And the fish that are in the river shall die, and the river shall stink thereupon, and the Egyptians shall not be able to drink water from the river.

19 And the Lord said to Moses, Say to thy brother Aaron, Take thy rod in thy hand, and stretch forth thy hand over the waters of Egypt, and over their rivers, and over their canals, and over their ponds, and over all their standing water, and it shall become blood: and there was blood in all the land of Egypt, both in vessels of wood and of stone.

20 and Moses and Aaron did so, as the Lord commanded them; and having lifted up with his rod, smote the water in the river before Pharao, and before his servants, and changed all the water in the river into blood.

21 And the fish in the river died, and the river stank thereupon; and the Egyptians could not drink water from the river, and the blood was in all the land of Egypt.
